Litoral, growing in rock-pools or mo st frequently on 

 stones and rocks in the lower part of the zone. It is a pe- 

 lagian plant which mainly occurs on open shore and best 

 developed on much exposed places. Sometimes, however, it 

 also penetrates into the deeper hays. Thus I found it at 

 Kirkenses in Sydvaranger pretty plentiful, but the specimens 

 were small and somewhat stunted. It often grows gregari- 

 ous in large number, for inst at Kjollefjord and Finkong- 

 kjeilen, so as to determine considerably the character of the 

 vegetation. I do not know when the species develops its re- 

 productive organs, probably in the autumn. At West-Fin- 

 marken I have seen it bearing sporocarps in the later half 

 of August and in September. 



Distribution: In the western part of the district pret- 

 ty common and abundant, in the eastern part less common 

 and somewhat local, but at some places abundant, and en- 

 ters pretty far into the deep fjords.
